As for schedule, both went undefeated in the SEC... that's about nuff said. But Auburn beat 5 top 10 teams(4 of which ended the season there). Bama's only win over top 10s where their last 2. Only 4 off their schedule finished in the top 25.
Also, besides the close call to the defending MNC LSwhoo team early in the year(more on this game later), Auburn didnt have another true 4th quarter threat all year. Bama needed miracles vs two 7 win unranked teams in Tenn and Auburn. Also, the Bama O struggled mightily vs South Carolina and Ole Miss, two more very average teams. Auburn looked more dominant week in and week out in '04 than Bama in '09.
And a nice ace in the hole arguement.... Bama didn't face an offense with near the power of Auburn's all year, however, Auburn faced several tough defenses. Bama for one was a top 10 D that year. Also, Georgia and Tenn were top flight defenses that year....oh yeah, and in '04 Auburn happened to beat a defense coached by Nick Saban. ;-)
So there's my arguement, backed by some pretty solid points I think. Feel free to debate with facts....but like I said, keep the gloves up. This should be a fun debate between what should be two proud fanbases.
WAR EAGLE!
